jquery实现的回车(Enter)替换为Tab键

  textboxes = $('.enterIndex');
  // now we check to see which browser is being used
  if ($.browser.mozilla) {
    $(textboxes).bind('keypress', CheckForEnter);
  } else {
    $(textboxes).bind('keydown', CheckForEnter);
  }
});
function CheckForEnter(event) {
  if (event.keyCode == 13 && $(this).attr('type') != 'button' && $(this).attr('type') != 'submit' && $(this).attr('type') != 'textarea' && $(this).attr('type') != 'reset') {
    var i = $('.enterIndex').index($(this));
    var n = $('.enterIndex').length;
    if (i < n - 1) {
      if ($(this).attr('type') != 'radio')
      {
        NextDOM($('.enterIndex'),i);
